custom storage/backends

[c-antin]

Summary 💡

Any plans on supporting custom backends?
See https://github.com/go-git/go-git/tree/v5.11.0/storage
Or https://github.com/libgit2/libgit2-backends

Motivation 🔦

Use case: in-memory and/or database storage for objectDB, refDB, etc. for faster access or reduced storage footprint.

Currently there are traits available for reading from and writing to the object database, but the main implementation can't yet be replaced.
It should be possible to one day put it behind a trait and thus allow alternative implementations, but it's not on the roadmap just yet, so I'd think stabilization happens before it.

Questions related to this are WASM support, as currently gitoxide can't compile to it for the most part, but will have better chances with swappable object storage backends.
